Do I need an underbase when screen printing?
Great question! In screen printing, an underbase is a layer of white ink printed underneath your design to make the colors on top look brighter and more accurate. Whether or not you need one depends on the color of the garment and the style of your artwork.
When You DO Need an Underbase
Printing on Dark Garments – If you’re printing on black, navy, or any dark-colored shirt, an underbase keeps your colors from looking dull or muddy.
Bright, Vibrant Colors – If your design includes reds, yellows, or neons, the underbase helps them pop against darker fabrics.
Multi-Color Prints – An underbase ensures consistency when layering multiple inks.
When You Might NOT Need an Underbase
Printing on Light Garments – On white or very light shirts, your inks will appear bright without an underbase.
Vintage/Distressed Looks – If you want a softer, more faded effect, skipping the underbase can give you that style.
Single Dark Ink on Light Shirt – For example, black ink on a gray or white tee usually doesn’t need an underbase.
Why It Matters
An underbase is basically like priming a canvas before painting. It makes sure the colors sit on top of a smooth, opaque surface so they look just as intended. Without it, your print could look muted, especially on dark shirts.
Final Takeaway
You don’t always need an underbase, but for most multi-color or vibrant prints on dark apparel, it’s the best way to guarantee your design looks professional and long-lasting. At Delivered By Decade, we’ll review your artwork and garment choice to recommend the right approach.
